JOHN DABUS, OF PIQUA, OHIO.

DETACHABLE HEEL-CALK AND HOOF-PAD.

SPECIFICATION forming part of Letters Patent No. 329,627, dated November3, 1885.

Application filed July 24, 1884.

To all whmn it may concern:

Be it known that I, JOHN DABUS, a citizen of the United States of America, residing at Piqua, in the county of Miami and State of Ohio, haveinvented certain new and useful Improvements in Horseshoes, Detachable Heel- Oalks, and Frog-Pads, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in the construction of horseshoes and in removable heel-calks therefor, and in means for attaching said calks in position.

The invention consists in forming in each inneredge of the heel of the shoe an inwardlyextending groove or recess to receive the outer flanged edges of the removable calk; in constructing each call; in its outside edge with a longitudinal recess to fit the inner edgeof the shoe, with top and bottom flanges to embrace the top and bottom faces of the shoe, and with a shoulder or stop at its outer end which abuts against theheel of the shoe; in forming on the inner edge or side of each calk top and bottom inwardly-extending flanges to receive a wedge-shaped key-plate and a curved keyseat, and in a key-plate for retaining the call; in position on the shoe, said key-plate having wedge-shaped edges to adapt the same to slide between the inner flanges on the calk attachments, and each of such edges having a notch or recess adapted to fit the curved key-seat.

In the accompanying drawings, Figure 1 represents a top plan view of a shoe constructed according to my invention. Fig. 2 represents a bottom plan view of a shoe with my removable calks and key-plate in position thereon. Fig. 3 represents a top plan View of a shoe with the calks, key-plate, and frogcushion in position thereon. Fig. 4 represents a perspective View of one of my removable calks viewed from the under side and inner edge thereof. Fig. 5 represents a perspective view of one of the calks viewed from the inner edge and upper face. Fig. 6 represents a top plan view, and Fig. 7 a bottom plan View, of the key-plate.

Arepresents a horseshoe constructed according to my invention. This shoe, as shown in Fig. 1 of the drawings, has at its heel portion (No modrl.)

grooves or recesses a, which are formed in the upper face andinner edge and extend inwardly a suificient distance to receive and form seats for flanges extending outwardly from the up.- per faces of the separable calks, as will be hereinafter described.

B represents my improved removable calks, which are provided with any suitably-shaped points or projections, or calks propcr-such, forinstance, as round, square, or sharp points as may be desired, such calks or points being represented by the letter I). Each calk is at its outer edge formed with two outwardlyextending flanges, one, 0, on its under face extending a sufficient distance to embrace the under face of the shoe when in position thereon, and the other, d, extending outward adistance corresponding with the width of the groove or recess a in the shoe, within which it fits.

eis a stop which extends outwardly from the rear end of the calk and abuts against the outer end of the heel of the shoe, and thereby limits the inward movement of the calk on the shoe, andholdsitin position thereon. Theseflanges c and d form a recess, f, within which the inner edge of the heel of the shoe rests. From the inner edge of each calk 13 extend inwardly two flanges, g and h, having between them a curved key-seat, i, the office of the flanges g and hand key-seat 1' being to receive and form a seat for the edge of a calk-clamping plate, to be presently described.

0 represents a key-plate for clamping the calks in position upon the shoe. This keyplate is, as shown, of wedge shape, and may be formed of any desired length to adapt it to fit shoes of different degrees of wideness at the heel, and in cases of contraction this wedge-shaped plate can be forced in tight enough to spread the shoe, and thus spread the hoof. Each side edge of this wedge-shaped plate 0 is formed with a downturned flange, j, of a thickness corresponding with the space between the flanges gand h, and between which it is forced when it is desired to clamp the calks in position.

represents a curved recess in each edge of the flanges j, which engages with the curved key-seat t, and thereby serves as an additional means for holding the calks in proper position upon the shoe. The calks B having been placed in position upon the shoe, with the flanges c and d resting against the heel, the wedge-shaped plate or key 0 isforced inward between the flanges g and h until the curved recess it engages with the curved keyseat 13,

whereupon the calks are securely clamped in .away from the shoe.

To facilitate the removal of the key-plate, I form on the under face thereof, and near the rear end, a transverse lug, D. lVhen it is desired to remove the key-plate, I take a pair of tongs and place one jaw thereof against the rear edge of said lug D, and the other jaw grasping the front of the shoe and drawing the key-plate inward. Then the'key-plate can be readily drawn out. Similarly the key-plate can be readily and firmly placed in position between the calks by grasping the lug D with one jaw of the tongs and with the other jaw against the end of the heel of the shoe and drawing the key-plate backward. By forming the flanges j downturned-I am enabled to bring the top face of the key-plate flush, or nearly so, with the top of the shoe.

E represents a heel pad or cushion, of rubber, leather, or other suitable material, which is attached to the top face of the key-plate, and is of such contour as to cover the same, and the flanges of the calks for the purpose of affording a rest for the frog of the horse and supporting it out of contact withthe metal, which is desirable when the frog is sore.

Having thus described my invention, what I claim as new therein isl. A horseshoe having removable heel-calks and a wedge-shaped plate adapted to pass between the inner edges of the calks and clamp the same to the shoe.

2. Ahorseshoe having alongitudinal groove or recess in each upper inneredge of the heel, in combination with heel-calks having flanges to engage within said recesses, and awedgeshaped plate adapted to pass between the inner edges of the calks and clampthe same to the shoe, substantially as and for the purpose set forth.

3. The combination, with a horseshoe having a longitudinal groove or recess in the upper. inner edge of the heel. of a heel-calk having on its upper face a flange adapted to fit;

within said recess, on its under face a flange adapted to overlap the shoe, and at its rear end a stop for limiting the inward movement of the calk upon the shoe, and means, substantially as described, for clamping the calk and against the curved seat on said calks, substantially as and for the purpose set forth.

In testimony whereof I afifix my signature in presence of two witnesses.
